Intersil IM6100 Vintage Dev Kit

Retronics series

This Dev kit was real state of the art stuff in 1977, but you had to be fairly dedicated to do much with it. There was no assembler or compiler. You had to write the program on paper, hand compile it and then load the memory with the required data using the keypad — not that there was all that much memory, only 256 words of 12 bits.
